Cause Work-Around Affects Rev W185 enables are tied low; should be tied high. 1. Cut trace between U1 pin 18 and ground via. X3 A EN1 and EN2 should be connected to +3.3V. Only EN1 is required. 2. Connect U1 pin 18 to U1 pin 16 (+3.3V). VBAT needs to be ~3.0V. If CR2032 Coin Battery used: X3 A X3 A X3 A X3 A Coin cells are 3V, cabled batteries are 4.5V. R44 values must be selected based upon battery used. For X4: Connect pin 18 of U1 to +3.3V. 1. Remove 0 ohm resistor on half of dualresistor component R44 nearest ATX power header. If Rayovac Cabled Battery used: 1. Install 100K ohm resistor on portion of R44 nearest National SuperIO. 2. Install 27K ohm resistor on portion of R44 nearest ATX header. For X4: Use two discrete resistors; standardize on coin cell. 3 Design Soft power not working. No pullup allowed on PS_ON. 1. Cut trace between RN72 pin 5 and via connecting to VCC3.3. For X4: Delete pullup. 4 Design PCI arbiter not working. No pullups on SLOT_REQ(1:4) Connect (4) 4.7K ohm resistors between SLOT1/SLOT2/SLOT3/SLOT4 pins B18 and B19 on the bottom of the board. For X4: SLOT_INT(1:4) on page 19 should be for SLOT_REQ(1:4). 5 Design None. SLOT_INT(1:4) pulled up twice. None. For X4: Remove redundant pullups. Motorola Inc.

Affects Rev X3 A X3 A For X4: Remove redundant pullups. 7 Design Slot 3 interrupt not responding. Slot 3 INTA/INTB pins connected incorrectly. 1. Remove all solder on SLOT3 pin A6. 2. Cover pin with Teflon or equiv. insulating sleeve. 3. Connect SLOT3 pin A6 to SLOT3 pin B7. For X4: Connect INTA# to SLOT_INT(3), INTB# to SLOT_INT(4). Motorola Inc.

WORKAROUND The work-around corrects INTA# only. A multi-interrupt card should not be used in SLOT 3. 1. Remove all solder on SLOT3 pin A6. Place Teflon sleeve over pin. 2. Connect SLOT3 pin A6 to SLOT3 pin B7 SLOT 2 SLOT 3 A1 SLOT 4 R21 B7 A6 Motorola Inc. Unrestricted Distribution Permitted 01 Feb 16
